To calculate the average speed, you need to divide the total distance traveled by the total time taken. In this case, the total distance traveled is 88 kilometers and the total time taken is 11 minutes.
First, let's convert the time from minutes to hours, as the average speed is usually expressed in kilometers per hour. There are 60 minutes in an hour, so:
11 minutes = 11/60 hours (approximately 0.1833 hours)
Now we can calculate the average speed:
Average speed = Total distance / Total time
Average speed = 88 kilometers / 0.1833 hours
Average speed ≈ 480 kilometers per hour
Therefore, the average speed of 88 kilometers in 11 minutes is approximately 480 kilometers per hour.
